INTRODUCE ABOUT FULLY-INTEGRATED INTELLIGENT VARIABLE FREQUENCY PUMP

Overall Introduction

BW(J)E and BL(T)E series fully integrated intelligent variable frequency pump is a new generation of pressurized water supply equipment newly developed by the Company which highly integrates variable frequency controller，water pump and pressure tank; with handsome appearance，the pump has reached the international advanced level provided with artificial intelligence，it can adjust automatically to meet the user's requirement for constant pressure and variable frequency water supply，so as to keep constant the pressure of water supply network and maintain the whole system at the optimal energy-efficient state。

 

Application fields

1）Domestic water supply: Roof pressurization for high-rise buildings,apartment。and villa, etc.

2）Public places: School, restaurant, station, hospital and gymnasium, etc.

3）Commercial buildings: Hotel, office building, and department store, etc.

4）Irrigation: Farm, orchard, and park, etc.

5）Industry: Manufacturing, food industry, factory water supply and other places requiring constant pressure water supply。

Operating conditions

 1)  Operating voltage AC220V±10％, 50HZ, with inter-phase unbalance less than 2％.

2）Ambient temperature-5^oC-40°C;

3）The altitude at the installation site no more than 1000m:,

4)  Ambient humidity 10-90％RH（non-condensing)

5) There is no medium with explosive risk in the ambient air, and there is no gas or conducting dust which is enough to corrode metal and damage insulation in ambient media. The product is designed to operate in the environment with the pollution class.

Model definition

Functions and characteristics

1)When water is used, the system is kept at constant pressure control, when water is not used, the system pressure is automatically maintained with the pump shut down.

 2)The operating pressure fluctuation range of variable frequency pump is no more than 0.01MPa.

3)The pump shuts down if it idles without water.

4)The pump has the function of detecting such as disconnection,  overcurrent, overload, and earthing.

 5) Frequency converter: With the protection class of lP65, it's safe with

 6)High integration: water pump and frequency converter are integrated small volume, easy to install and space saving.

7) Full- automatic control: The pump can automatically state according to the user's pipe network pressure to reach the optimal operating state and make the system more energy-saving. When no water is used, it automatically maintains the pressure and goes to sleep, with obvious energy-saving effect. When the pump breaks down, it automatically performs real-time tracking, judgment and handling.

8)Convenient and simple oporation: Man-machino interaction can bo roalized directly through buttons and display at the froquoncy convorter, and tho user can make pressure rolated settings according to the actual operating conditions, and obtain rolovant information: in caso of any abnomality,the user can obtain information about the abnormality.

9)Constant power oporation: When the controllor roaches the limit power, it adjusts according to actual operating conditions;with water supply for tho user guaranteed wherever possible, the output powor isunchanged to roalizo protection of the motor .

Action specification

The automatic identification modulo senses the system pressure through pressure compares it with the set pressure, and outputs continuous sensor, variable frequency analog signal to thefrequency converter, and then the controller changes the operating frequency of motor according to the change of analog signal so as to reach the requirement for constant water supply.When the users water consumption is large, the pump automatically increases the rotating speed and power to meet the requirement for constant water supply.When no water is used, the pump automatically sleeps after the system reaches the set pressure, and only when the water pressure drops to 80% because the user uses a small amount of water or the pipeline leaks, the variable frequency controller sends signal to orderthe motor to operate to compensate the pressure to the set pressure, so a to realize energy saving to the greatest extent.
